EJS

Get Started:

Install:-

    npm install ejs

Use:-

Pass EJS a template string and some data. BOOM, you’ve got some HTML.

    let ejs = require('ejs');

Browser support:-

    <script src="ejs.js"></script>
    <script>
    let people = ['geddy', 'neil', 'alex'];
    let html = ejs.render('<%= people.join(", "); %>', {people: people});
    </script>

Options:-

• cache Compiled functions are cached, requires filename
• filename Used by cache to key caches, and for includes
• root Set project root for includes with an absolute path (e.g, /file.ejs). Can be array to try to resolve include from multiple directories.
• views An array of paths to use when resolving includes with relative paths.
• context Function execution context
• compileDebug When false no debug instrumentation is compiled
• client Returns standalone compiled function
• delimiter Character to use for inner delimiter, by default ‘%’
• openDelimiter Character to use for opening delimiter, by default ‘<’
• closeDelimiter Character to use for closing delimiter, by default ‘>’
• debug Outputs generated function body
• strict When set to true, generated function is in strict mode
• _with Whether or not to use with() {} constructs. If false then the locals will be stored in the locals object. (Implies --strict)
• localsName Name to use for the object storing local variables when not using with Defaults to locals
• rmWhitespace Remove all safe-to-remove whitespace, including leading and trailing whitespace. It also enables a safer version of -%> line slurping for all scriptlet tags (it does not strip new lines of tags in the middle of a line).
• escape The escaping function used with <%= construct. It is used in rendering and is .toString()ed in the generation of client functions. (By default escapes XML).
• outputFunctionName Set to a string (e.g., ‘echo’ or ‘print’) for a function to print output inside scriptlet tags.
• async When true, EJS will use an async function for rendering. (Depends on async/await support in the JS runtime. Tags
• <% ‘Scriptlet’ tag, for control-flow, no output
• <%_ ‘Whitespace Slurping’ Scriptlet tag, strips all whitespace before it
• <%= Outputs the value into the template (HTML escaped)
• <%- Outputs the unescaped value into the template
• <%# Comment tag, no execution, no output
• <%% Outputs a literal ‘<%’
• %> Plain ending tag
• -%> Trim-mode (‘newline slurp’) tag, trims following newline
• _%> ‘Whitespace Slurping’ ending tag, removes all whitespace after it

Includes:-

Includes are relative to the template with the include call. (This requires the ‘filename’ option.) For example if you have “./views/users.ejs” and “./views/user/show.ejs” you would use <%- include(‘user/show’); %>.
